I WILLIAM KUTALEK, 0F AUSTIN, TEXAS.

FORIVIER FOR PLASTIC MOLDING.

Application filed July 31, 1923. Serial No. 654,949.

To all whom it may concern:

Be it known that 1, WILLIAM KUTALEK, a citizen of the United States ofAmerica, residing at Austin, in the county of Travis and State of Texas,have invented certain new and useful Improvements in Formers for PlasticMolding, of which the following is a specification.

This invention relates to certain new and useful improvements in formersfor plastic molding of either wall or picture frame type and hasparticular reference to the provision of a mold former or cutting 'toolforcutting a blank molding strip of plastic material into a grooved orridged molding configura- .tion.

A further object of the invention is to provide a former for plasticmolding of a picture frame type wherein a molding blank of rectangularformation supported upon a baseboard has a guide frame associated withthe blank and with which frame a former or cutting membercarried by ablock hav-' ing aplurality of straight edges cooperate with the cuttingmember having its longitudinal axis disposed at an angle to the straightedges of the block to 'permitthe cutting member tomove over the moldblank in forming a corner thereof.

With the above and other objects in view as the nature of the inventionis better understood, the same consists of the novel form, combinationand arrangement of parts hereinafter more fully described, shown in theaccompanying drawing and claimed.

In the drawing, wherein like reference characters designatecorresponding parts throughout'the several views,

Fig. 1 is a fragmentary top planview' showing a partially formed plasticpicture frame molding and base support therefor with a former forcutting the molding blank at the side portions thereof spaced from thecorners,

Fig. 2 is a fragmentary top plan view, similar to Fig. 1 showing thetype of former for cutting the corners of the frame mold- 111g,

Fig. 3 is a detail sectional view taken on line IIIIII of Fig. 1 showingthe former cooperating with a guide strip carried by the base supportfor the frame molding,

Fig. 4 is a detail sectional view taken on line IVIV of Fig. 1 showingthe molding blank,

' Fig. '5 is a side elevational view of the mold former shown in Fig. 2,and

Fig. 6 is a detail sectional view taken on line VIVI of Fig. 5.

Referring more in detail to the accompanying drawing, a pictureframemolding of plastic material in blank formis mounted upon a baseboard 1 adjacent the edges thereof, the blank molding 2 beingspaced fromthe base board 1 by the strip 3 that prevents ready removal of thefinished molding. The base board 1 and molding blank 2 are ofrectangular formation, the base board 1 carrying a rectangular guideframe upon the upper face thereof inwardly of the molding blank 2 formedof side strips 4 and end'strips 5 anchored to the baseboard as at 6.

To form the mold configuration 2 in the sides and ends of the moldingblank 2, the

type of former illustrated in Figs. 1 and 3 is employed, the block 7having a forward straightedge .8 and parallel side edges 9 being fixedto the upper face thereof, alongitudinally extending arm 10 projectinglaterally thereof as at 11 with a depending or cutting blade 12 carriedby the arm projection 11 with the inner edge of the cutting blade 12spaced from the straight edge 8 of the block 7. The block 7 is flatlyplaced upon the base board 1 with. the forward straight edge 8 thereofengaging the guide strips 4 or 5 with the cutting blade 12 overlying themolding blank 2. By reciprocating the block 7 the blade 12 cuts thedesired mold configuration 2 as shown in Figs. 1 and 3, movement of theblock 7 being limited by the opposite edges 9 thereof engaging the guidestrips 4 or 5 according to the position of the block.

In forming the mold configuration 2 at the angle corners of the moldingblank 2, the type of former illustrated in Figs. 2, 5, and 6 isemployed, the rectangular block 7 a having a pair of straight edges 8with the arm 10 diagonally secured to the upper face of the block W withthe longitudinalaxis thereof extending at an angle to the straight edges8 The arm 10' carries an end extension 11 having a depending cuttingblade 12" that is of greater length than the cutting blade 12 tocompensate for the angle position thereof during use. The block 7 isflatly placed upon the base board 1 with the straight edges 8 movingover the guide strips 1 and 5, while the cutting blade 12 moving overthe corners of the molding blank 2 forms the molding configuration 2".It will therefore be seen that by the angular disposition of the bladecarrying arm with respect to the supporting block 7, the

angle corners of the molding blank 2 are cut into the moldingconfiguration similar to the side sections 2 After the formation of thei molding, the same may be readily removed from the base board 1 bydisengaging the strip 3 from the ,board providing a com- 7 pletedrectangulai: frame inoldin -While there is herein shown and describedthe preferred embodiment of the present invention, it is nevertheless tobe understood that ,minor ehanges may be made therein without departingfrom the spirit and scope of the ingention as claimed.
